Arms Assigned Interventions
Experimental: NovaShunt's Automated Fluid Shunt
The Automated Fluid Shunt (AFS) Device
Device: NovaShunt's Automated Fluid Shunt implantation
The Automated Fluid Shunt (AFS) Device consists of an implantable sealed housing which contains an internally powered pump with supportive electronic components and circuits, an implantable Peritoneal Catheter, implantable Bladder Catheter and a non-implantable Charger used for wireless recharging an AFS battery and collecting data from the Device.
